Might want to swap the ICM out. If you fiddled there and changed a coil, maybe disrupting the connector or the base set something in motion?

It's a 95, could very well be a PCM too!

The fuel pressure is kinda high, isn't it?

That is a bit high... A vin K should run from 48-55 Psi... at idle it can see 40-45 Psi... 60 Psi at idle may causing it to run rich..

ill change the regulator/fuel rail have one that was just pulled off a know running 2000 3.8

well went to change fuel rail and found that the vaccum hose plug that goes into the
intake had poppped out so put it in and runs like it should. this happen when i wanted to see
if just doing the cam sensor would make it run and it popped threw the intake but didnt click in my head
that it could of done that so then put crank sensor in and it ran but not good.
so the bonne lives again wife will be happy she loves the car
thanks for the help

Replace your PCV. Maybe your PCV is plugged, and will pop that out again.

Glad it is running better.

ill do that, now i have a esc failure code

Post by **Jrs3800** » Mon Dec 23, 2013 7:17 pm

Is it a code 1351/1361?

TUFFBONNEVILLE · Post by **TUFFBONNEVILLE** » Mon Dec 23, 2013 10:26 pm

325 code

Post by **Jrs3800** » Tue Dec 24, 2013 2:48 pm

Thats a problem with the knock sensor circuit... On the older cars there was 0ne knock sensor on a 5v circuit... On the 95 Series II there were 2 knock sensors on the 5v circuit... The PCM reads in the area of 2.5v from the circuit, chances are you may have issues with the knock sensor circuit or a knock sensor...

Any codes other than this one?

just that code so this would cause a miss too
i pull one wire at a time at coil packs has spark put the even side is weaker than
odd side
at idle and maybe up to 2000 rpm misses but clears up above 2000rpm

well i checked voltage at knock sensors the one for odd side of block
2.5 volts
even side of block 0 volts
could this be a pcm problem
does this wire go to the coil pack computer
or strait to pcm
